Gas pumps ??
Since I am running twin turbo I have always been a little **** about the fuel rating. I run 93 and was wondering is the octane distributed at the hose end or from the underground tank. I do not want any 87 octane in the tank at all. I used to go to a station that had separate hoses for all the different octanes, but that is impossible any more.

Huh? There should be a separate tank for each octane level but I guess octane booster could be added at the nozzle at the time of delivery so only the lowest octane needed to be in the storage tank. Not sure why this matters to you since there really are no other options anymore, if your worried, carry you own octane booster and buy the 87 octane then add what you think you need.

LONG ANSWER - You ARE getting a small shot of whatever was pumped by the vehicle just prior to yours (whatever is residual in the hose). That said, the nature of how gasoline mixes is such that you do not need to worry about your engine getting a sudden shot of 87 octane fuel. It will blend with the 93 octane gas in the tank and your engine will never know it is there. The small amount of 87 octane fuel left in the hose mixed with a tank full of 93 octane fuel will have a negligible effect on the 93 octane rating of the fuel in your tank.
SHORT ANSWER - No need to worry about it.

I always fill up at Kwik Trip in my area. The only company that posts "Top Tier Gas - Guaranteed" on their pumps. We now have 4 Kwik Trip stations in the city I live in. I haven't visited the newest one yet, which opened a couple of weeks ago. Only 1 of the 3 has separate dispensers & hoses for each grade of gas (87, 89 & 93). I always fill up at the station that has the separate dispensers and hoses with 93 octane gas.

but if your OCD keeps you fretting about getting a small amount of regular in your tank, then just bring a gas can with you, pump the first gallon or so into it, and then fill up your tank. If you've got another vehicle that uses regular (or a lawnmower or any other small engine equipment), you can always use what's in the gas can in it.Or you can just take 4XLR8N's advice and forget about it.

Not making light of your question. If you're worried about the dispensing of the fuel at the pump, you definitely don't want to know about the dispensing from the refinery to the distribution centers. You'll wind up figuring out how to make gas for yourself.
The solution to pollution is dillution. Make sure you fill up your tank from empty to ensure the max dillution of any lower grade fuel in the hose if it really is a concern or add some octane boost at the time of filling. Me on the other hand just fill up and not fret it. Then again I'm running 100% stock.

What little bit of possible lower octane gas that may be in the hose will not really be a big deal when mixed with the high octane stuff.

These stations with one hose rip off a ton of money.
They sell 2.85 million gallons premium a day. Lets just guess at 12 gallons is the average sale.
Thats 237,500 sales a day, say half from stations with one hose, so 118,750 illicit sales. I estimate 1/2 gallon is trapped in the hose, so that is 59,375 gallons a day and say $.25 difference in price.......is roughly $15,000 ripoff per day.
Or the oil companies make about an extra $5.5 million per year if they use one hose.
I thought it would be a lot more.

Actually, it's not a ripoff at all when looked at in the aggregate. That 1/2 gallon of premium in the hose that doesn't go into the tank of the customer who paid for it does goes into the tank of the next customer who paid for regular. So the customer buying premium is ripped off (a little) but the next customer buying regular benefits (a little). The sellers aren't profiting at all by using one hose.

But the larger point I was making was that in the aggregate sellers are not in fact profiting by the use of one hose, refuting the claim made by ztheusa.

Premium in a car designed for regular actually decreases performance, as it has BTUs/pound. Thus, both parties lose.

Maybe you're just not happy with the fact that I debunked your theory about sellers making a profit by using one hose. Sorry if it hurt your feelings (or ego).
